Proteins
The nitrogenous bases. I think.
Thymine is a nitrogenous base that is part of DNA but not found in RNA. In RNA, thymine is replaced by uracil.
phosphorus
No, phosphorus is not part of the nitrogenous base. The nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine, which contain nitrogen atoms but not phosphorus. Phosphorus is primarily found in the sugar-phosphate backbone of the DNA molecule.
In nitrogenous bases, the nitrogen-containing molecules that are part of DNA and RNA structures, the bases are called adenine (A), thymine (T), cytosine (C), guanine (G) in DNA; and adenine (A), uracil (U), cytosine (C), guanine (G) in RNA.
In deoxyribose nucleic acid. DNA, as part of the backbone the nitrogenous bases are hung on.
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
strand of DNA
nitrogenous base consist of only three element nitrogen, oxygen and hydrogen, so other elements are not part of nitrogenous base.
The first part of nucleotides are a five carbon ribose sugar. The second part is a phosphate molecule. The third part is one of four nitrogenous bases such as cytosine, adenine, and guanine.
There are actually 6: Adenine, Thymine, Cytosine, Guanine, Phosphates, and Deoxyribose Sugar Molecules. 1 Phosphate and Deoxyribose Sugar Molecule create a nucleotide, and Adenine, Thymine, Cytosine, and Guanine are nitrogenous bases. DNA is shaped like a double-helix (a ladder). The two sides of the ladder are the nucleotides and the rungs are nitrogenous bases. The order of nitrogenous bases determines the organisms life characteristics (eye color, skin color, hair color, etc.)
